Sib ntsuam：

Straight seam high frequency (ERW) yog ib tug rau ntawm mus qhov tswj hauv txoj cai, induction welding thiab contact welding los yog cov neeg ua li. Yog mus hot-rolled wide coils los yog raw materials thiab muaj pre-bending, continuous forming, welding, heat treatment, sizing, straightening, cutting, thiab cov nyob roj. Ntawm comparison ntawm spiral process, no yog tau qhia thiab shorter welds, high dimensional accuracy, uniform wall thickness, good surface quality, thiab high pressure resistance. Los yog, lub disadvantage yog mus yooj thiab thin-walled pipes ntawm small thiab medium diameters, thiab gray spots thiab lack of fusion yog kawg li los yog ntawm welds, groove corrosion defects. Rau hwm, mus yooj thiab lawv no yog city gas, crude oil thiab refined oil transportation, thiab cov.

Tus ntawv qhov kev tsev yog tau ua rau li yeej lub qab ntsuam thiab lub qab neeg, mus rau li qab neeg thiab nyob rau txoj caij lwm thiab peb hais tias tau xav li cas cas thiab cas cas. Yog tau no, peb kom paub zoo los yog li cas cas thiab cas cas, thiab li cas cas thiab cas cas, thiab cas cas thiab cas cas. Yog tau no, peb kom paub zoo los yog li cas cas thiab cas cas, thiab li cas cas thiab cas cas, thiab cas cas thiab cas cas. Yog tau no, peb kom paub zoo los yog li cas cas thiab cas cas, thiab li cas cas thiab cas cas, thiab cas cas thiab cas cas.

Thaum tas cov txiv npawm ua kev tshwm, no yog hloov rau:

UOE qab twg: Peb yog kawm los txiv tsis ntawm tau li cas, peb nyob rau hauv ib tug xyoo, O xyoo, khwv daim, khwv daim, thiab lub meej cai sib ntsuam.

JCOE qab twg: Yog, pre-welding, xyoo, thiab sib ntsuam los ntawm J-C-O-E

HME qab twg: Nyob rau hauv ib tug xyoo ntawm lub mandrel rolling method ntawm C-C-O, thiab sib ntsuam thiab teb chaw sib ntsuam.
